An LRAD is a long-range acoustic device, a powerful portable speaker designed to scare people away with sound, and it’s becoming increasingly popular among police departments. It is often described by critics as a sound cannon, offering a user “the ability to issue clear, authoritative verbal commands, followed with powerful deterrent tones.”
One popular device, the LRAD-100X, was used in Ferguson, and on two days last week, it was used to warn off demonstrators in New York City protesting the death of Eric Garner. According to its manufacturer, the LRAD offers police “near instantaneous escalation across the force protection spectrum” to “shape the behavior of potential threats.”
What would that sound like?
